Daniel wanted some pics of my bonnet scoop, still needs some work. Does wonders for under bonnet temps.

I have a plug made up if it rains. I think it makes the Soarer look a bit more mean, biggest thing though is that it dropped underbonnet temps by 40 degrees C

Jeff looks good though not my taste however the carbon vented bonnet is what is soon going to be on my soarer along with carbon boot lid and carbon fibre doors..

Weren't the doors illegal here and worth about $3000 each?

hmmm not bad , i wouldnt put one on my soarer but i would consider a vented item like the one Muzzy posted a pic of, except i wouldnt get carbon as i would just paint it white anyways. Fibreglass would do me fine.

Have you removed the rubber seal at the rear of your engine bay yet? It allows the hot air to pass out the back of engine near the firewall easier once you pull that bad boy out.

I like the vented bonnet in Muzzy's pic better. It suits the lines of the soarer, those old skool style scoops belong on old skool cars

However at least your scoop is functional and not just aesthetics Jeff!

I also thought all carbon/fibregalss bonnets were illegal, due to the way they disintigrate into sharp peices upon impact?

Depends on the weave of the material used. Lamborghini, ferrari, Maserati, lotus, Porsche, Audi, BMW.......etc all use composite materials in critical panels like the bonnet, front and rear quarter panels, and bumpers.

Unfortunately, most places just lay up basic weaved matt, cover it in resin, pop her in the mold and bake it. This means that even if the bonnet/door/bumper looks cool and weighs less, it has nowhere near the structural integrity that carbon fibre is known for. Hence, breaking apart in a crash.

It may have made your underbonnet temps lower, but come summer I wouldn't be surprised if it makes your engine run hotter.

Andrew, How will it increase temperatures during summer?

Engine bays are designed so that all the air enters through the front (ie the radiator) and out the back under the firewall.

Now every litre of air that if entering through the scoop is a litre of air that is no longer entering through the radiator to cool the engine down.

While its probably not a 1:1 ratio, there will be a difference. Whether or not its going to be noticeable, only time will tell.

I don't mean to be rude, but what a load of crap. Seeing as I had this installed at the end of summer and tested it in 36 C days I know what the benefits are. It reduced the temps above the turbo's and injectors from about 80 C down to around 43 C. You can now put your hand on the intake manifold after an hour at 100kph whereas before it would peel your skin of. How is the scoop changing what air is going through the radiator, if anything it will have a venturi affect and pull more air through. The Soarer engine bay is one big heatsink and in my mind is not well designed. I had a similar response from all the experts with the predator intercooler/ radiator setup, ie it wouldn't work and it would be a big heatsoak. Guess what - it isn't. Water temps on a 30C day sit at 80C, much lower than stock. I would suggest that unless you have some first hand evidence or figures to prove your ideas are factual that you STFU. BTW, why do WRX's etc have bonnet scoops?

Like I said, you may not see a difference.
36degC days are not what I'd call summer.
Your cooling system is obviously in very good condition.

Anything factory is designed to work like that from factory and thus cannot be compared.

Get off your high horse mate, I never said what you did was a dumb idea, I just suggested that it may potentially have a negative affect on other areas.

It so far hasn't in your case, so ignore me.

Top mount intercoolers.. thats why

but they also have vents too to let the excess air out that is dragged in from the scoop

also that bonnet scoop would be illegal here in qld, as you have cut one of the braces in the bonnet. you will have to get it braced better than original and passed by an engineer with a mod plate to make that legal. As for the height of the scoop and angle i think that would pass.

Sorry Christian I think you are wrong on that, the law says that as long as the strength of the bonnet is not "substantially" reduced it is OK. I checked with the local QLD transport inspector and said it was fine. Height etc is well under limits.
Yes wrx's have scoops for topmounts, which the majority of ppl remove and have no problem with overheating, I just sold my 02 bugeye that I owned for 4 years. Only 2000 and older rexes had vents.

Hi Jeff.. yeah the law is not clear and i personally wouldnt like to be pulled over by a cop down here with that. Each officers / inspectors interpretation of the law differs greatly down here. you are allowed to change/cut the skin, but if the crossbracing is cut it needs to be re-inforced to stronger than original and passed by an engineer. A real picky cop WILL still defect you for that if they want to based on the attached pic showing where the bracing was cut..

also mustaffa, we are not allowed carbon fibre bonnets unless adr approved.

Having said all this who cares about stupid laws.. i can get done for non mod plated surge tank in boot, screamer pipe, gutted cat, battery box not vented to outside of vehicle, 20's... blah blah blah..

I do think the bonnet looks good but, so good work.

Christian ;
Mate is that all you could get done for??????????
hahahahhahahahhah
god help me if thay ever stop the van....
the only place i know that has Australian complied fiber glass bonnets is Blits Automotive Here on the coast.
and from what Peter at blits has stated to me
Any rear facing opening on a bonnet is a big NO NO
So that means all the bonnets we want to put on the car(ex Japan styles) are illegal
Front facing openings can only be a certain height it has some thing to do with a ball and rolling it up and over the scoop (some thing like that)
its just so the next person you run over doesn
t get hurt from your scoop.HAHAHA (go figure)
the bugger will be dead if we hit them any way.

I got pulled over in my old TT when it had a similar scoop. The cop (In Cairns Qld) Put a little metre type thing with a level bubble on it at the highest part of the scoop, Then said it was on legal height so no defect. He did not pull the bonnet to check the underneath. Jeff it was about the same height as the one you have on. The Cop was from Brissy sent up to blitz the poor long suffering motorist up here, who have pride in their cars (strangley I did not see many rust buckets pulled over!!).

Thats another myth.

The back of the bonnet/base of the windscreen is a high pressure area, so any gap there will force air into the engine bay as opposed to sucking it out.
Much like with the bonnet scoop, any air entering the engine bay by means other than through the radiator makes the cooling system work harder.

Removing the rubber strip will have benefits at low speeds, but at high speeds it has the potential to make things worse.

Jeff, I put in some of that aluminium mesh you get from supercheap/autobarn. It gave it a finished appearance and would stop any wanker from putting paper or lit cigarettes etc into your engine bay. Which some idiots have done.
